1. A device for providing movement simulating crawling motions and providing for enhanced movement of a person'"'"'s truncal muscles and spinal joints, which comprises:

  • a generally horizontal base for supporting said person in an all fours crawling posture in which there is minimal gravity-induced axial loading of said person'"'"'s spine said base having incorporated therein a circular track having a centrally located pivot point;

    a stationary rest means, fixed to the support means, for engaging and supporting said person'"'"'s two hands or two knees;

    two support arms attached to said base'"'"'s pivot point for pivoting on the circular track in a circular arc about the pivot piont for engaging and supporting the remaining pair of said person'"'"'s hands or knees and for permitting said person to cause simultaneous lateral motion in extension or flexion of one limb independently of an opposed lateral motion in flexion or extension of the companion limb, with associated relative motion between axial portions or said person'"'"'s trunk while said person remains in said crawling posture;

    wherein upon such times as the pivoted support arms are supporting a pair of said person'"'"'s knees then said person'"'"'s crawling motion causing pivoting of the support arms in a circular arc will cause said person'"'"'s pelvis to move off the axial line of the thorax, therein causing relative motion in said person'"'"'s frontal plane and also said person'"'"'s rotational plane;

    wherein said relative motion between axial portions of said person'"'"'s trunk occurs in at least two of said person'"'"'s bodily planes simultaneously.
